WATER-C LOS ET.

SPECIFICATION forming part of Letters Patent No. 448,908, dated March 24, 1891.

Application tiled November 6, 1890. Serial No. 370,518. No model.)

T0 all whom t may concern.-

zen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Water-Closets, of which the following is a specitication.

The object of my invention is to so construct a water-closet as to render the same noiseless in its action; and this object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal sectional view of a water-closet bowl constructed in accordance with my invention, part of the reservoir with its valve and overflow-pipe being also illustrated; and Fig. 2 is a rear view of the bowl.

A represents the body of the bowl, having around the top the usual tiushing-rim a., and having at the front a siphon discharge-passage comprising the short leg b, communicating with the receiving-chamber of the bowl, and thle long leg d, communicating with the soil-pipe, these two legs being connected at their upper ends, as usual. At the front of the bowl and between the flushing-rim and the upper portion of the discharge-Siphon is a chamber f, having a number of jet-openings t' above the long leg d of the Siphon, and so located in respect to the latter that thejets discharged therefrom will, cover almost the entire area of said discharge-leg, so as to drive the air downward therefrom, and thus start the Siphon action in order to drain the bowl. At the back of the bowl is a neck or branch g, which receives the water-supply pipe h from the elevated reservoir B, and this waterreceiving neck is forked at its lower end, so as to form two pipes or passages m and n, which extend around under the sides ot the bowl and up toward the top of the same at the front, one of these pipes-say, for instance, thepipe-m-communicating with tl1ejetchamber f and the other with the iiushing-rim d. lVat-er entering the supply-neck g therefore is directed through these branch pipes or passages to the flushing-rim an d jet-chamber, the proportion of water-supply received by each being dependent upon the relative areas of the two pipes or passages m and n, which may be so proportioned in respect. to each other as to give to the flushing-rim and jetchamber the proper volume of water required by each, each supply being entirely independ ent of the other, so that neither part can receive an excess at the expense of the other. Each of the pipes or passages m and 'n has a drainage-passage p, communicating with the lower portion of the short leg` of the siphon, so that the water normally stands at the same level in the bowl and in said pipes m and n, which thus serve as water seals or traps for the lower end of the pipe 7L, the latter being lled with water, owing to the fact that no air can enter the upper end of said pipe when the valve s is closed, the overiiow-pipe t being sealed against the iniiow of air, such sealing being effected in the present instance by a water-seal box w and by a valve .fr at the top of the pipe. The pipe 7i is thus sealed against the inlet of air either at top or bottom, the bends in the supply-pipes m and n serving as traps for the lower end ot' said pipe h, so that when the valve at the top of the pipe is closed to cut off the inlet of water to said pipe, the latter, the supply-neck, and the bends of the pipes 'm and n below the flushing-rim and jetchamber remain filled with water. A solid column of water being thus maintained between the reservoir and bowl, there is on starting the How into the bowl no noise, such as usually accompanies the displacement of the air in the supply-passages and the first rush of mixed volumes of air and water into the bowl. rlhe tank and passages can be drained, however, when d esired, by removing the water from the bottom of the bowl and Siphon-pipe, so as to uncover the drainage-passages p.

If desired, the overflow-pipe may communicate with the bowl independently of the pipe h, in which case the sealing of said overfiowpipe will not be necessary.

Having thus described my invention', I claim and desire to secure by Letters Patent# 1. The combination of the bowl having a iiushing-rim, the supply-reseiwoir, the valved pipe conducting water from the reservoir to the bowl, but sealed against the inlet of air at the upper end when the valve is closed, and a curved pipe or passage connecting the supply-pipe and iiushing-rim and forming a bend IOO below the latter, so as to constitute a water seal for the supply-pipo, the latter being` otherwise closed against the inlet of air at its lower end, substantially as specified.

2. The combination of the bowl having a siphon discharge-pipe andjet-chaniber thereforJ a snpply-reservoir, the valved pipe conductingl water from the reservoir to the bowl, but sealed against the inlet of air at the upper end when the valve is closed, and a curved pipe or passage connecting the supply-pipe and jetfchamber, and forming a bend below the latter, seas to constitute a water seal for the supply-pipe, the latter being' otherwise closed against the inlet of air at its lower end, substantially as specified.

The combination of the bowl having a flushing-rim, a siphon discharge-pipe and a jet-chamber for the latter, a water-reservoir, a vaived pipe conveying water from said reservoir to the bowl, but sealed against the inlet of air at the upper end when the Valve is closed, and curved pipesor passages eonnect- 'ing the supply-pipe respectively with the 'flushing-rim and jet-cha1nber of the bowl, bn t forming bends below the saine, so as to retain the water and constitute seals whereby any entrance of air to the lower end of the supplyppe is prevented, substantially as specied.

4. The combination ofthe bowl, the supplyreservoir, the Valved pipe conveying water from the reservoir to the bowl, but sealed against the inlet ot' air at its upper end when the Valve is closed, a curved pipe or passage connecting the supply-pipe with an outlet at the top of the bowl and forming a bend below said outlet, but above the bottom of the bowl, so as to retain the water and seal the lower end of the supply-pipe, and a drainagepassage leading,r from the lower portion of the bend into the bowl, substantially as specified. In testimony whereof I have signed my name to this specification in the pr A/senee of two subscribing witnesses.
